Applicationfil ed August 2'7. 1907- Serial No. 390.298-

To all whom it may concern:

Be-it known that I, ALEERTJ. Form, a citizen of the United States, residing in New York, in the borough of Manhattan, county and State of'New York, have invented certain new and useful Improvements in Coating-Machines, of which the following is a specification.

This invention relates to an improved coating machine, by which metallic sheets, card board or any other ,stii'f sheets are coated with paste, paints, varnishes, lacquers or colors in a uniform and efiective manner.

The object of the invention is to provide an improved construction of raising and-lowering mechanism for the color-fountain used in such machines, whereby said fountain may be properly adjusted with respect to the fountain-roll and easily removed for 20w cleaning.

With this end in view the invention consists in the novel construction to be hereinafter described and claimed.

In-the accompanying drawings, Figure 1 represents a side-elevation of my improved coatingmachine, and Fig; 2 is an end-elevation of the same, with some of the parts broken off and other parts removed for the sake of clearness.

Similar letters of reference indicate corresponding parts Referring to the drawings, f represents the supporting-frame of my improved coatmg-r'nachlnei The supporting-frame consists of two upright side-standards j" which.

are firmly connected with each other by transverse braces f The side-standards f are provided at their sides with horizontal brackets f on which a feed-table t is supported. At the upper part of the side-standards f 1 arallel horizontal brackets f above the fee -table, are arranged, in which are supported bearings for the shaft of the founta1n-roll.b, which extends with its lower part into a color-fountain c which is supported on horizontal arms c that are arranged at the upper ends of downwardly-extending arms 0 which are guided by means of slots (1 on headed screws 0 of the side-standards. The lower ends of the downwardly-extending guide-arms c form contact with eccentric cams c that are keyed on a transverse shaft 0 which is provided at both ends with crank-arms c provided with handles a", by which the arms '0 and bracket-arms can be raised or lowered for the length of the guide-slots a, so as to place thereby the color-fountain cin normal position belowthe fountain-roll b, min a position somewhat below the same. so as to permit the convendesired to lower 'the supporting bracket-.

arms of the color-fountain preparatory to the removal of the latter. The raising of the supporting-brackets of the colorfountain is accomplished by the cams 0, while thelowering of the same is accomplished by gravity when the crank-shaft c is turned so as to bring the lower portions of the cams 0" below the-arms c Y i The bearings b of the fountain-roll b are guided in the supporting-ways of the same and adjusted by hand-screws 1) against the tension of cushioning-springs b, which are arrangedat the opposite sides of the bearings b. When the fountain-roll is properly adjusted, it is securely held in osition by a jam-nut I) provided with a han -lever for setting the same. At the upper part of the fountain-roll b is arranged a color-regulating roll e,.the shaft of which is supported in bearings which are capable of adjustment towards the fountain-roll, by set screws e against the tension of suitable cushioning-springs 6 the bearin s being located in guides as the toppart 0 the horizontal brackets f Positive rotary motion is imparted to the regulatingroll 6, by a suitable transmitting gear, so that by the pressure exerted by the regulatin roll on' the fountain-roll, the taking up 0 the color from the color-fountain c is regulated and'a uniform layer of color supplied to the transfer-roll g with'which the fountainlroll b forms contact. The transfer-roll is supported in cushioned, adjustable bearings o the side-standards f in the same manner as the fountain-roll, and forms contact with the presser-roll g Motion is transmitted to the Presser-roll, transfer-roll, fountain-roll, regubetween the rolls 9 ,1

lating-roll and the. feed-rolls for the sheet, from the driving-shaft S by a train of gearwheels which is arranged on one side-standard, while at the opposite side-standard the by sultable gearing the drive-pulleyi of a delivery-belt 2, so that the sheet, which is fed by the attendant to the feed-rolls d, d

passes through the presser-roll g and the up per transfer-roll on to the delivery-belt, receivmg-a layer of color during its passage through I The feed-table t and the contact points ofthe feed-rolls d, d and rolls g, g and the upper part of the deliverybelt 13 are approximately on the same level, so

that the sheet is passed through the different rolls without being bent or buckled.

The presser-roll g is provided with a doc tor-blade n, which is supported on a transverse shaft n that turns in bearings of the supporting-frame, and provided .with outwardly-extending levers n -the ends of which are engaged by adjustable set-screws n provided with hand-wheels, said set-screws being guided in interiorly-threaded. sockets that are attached by clips to one of the transverse brace-rods of the supporting-frame low the presser-roll g and the doctor-blade n is arranged in suit-able su orts 0 attached to the side-standards f a r1 -pan 0, to which a slight sidewise inclination is given so that the drip collected therein can be drawn ofi throu h a spout beneath the pan.

At oth endsof the fountain roll 7) and transfer-roll g are arranged, sidewise oi the angular space formed between these rolls and above the contact oint of thesame, colorretaining plates r,w ich are applied by sleevesha ed hubs at their upper ends to short studsha ts T which are sup ort-ed in suitable bearings of the side-stan ards f and by which the plates 7' are supported in proper position for preventin the flow of color over the flat end-faces oft e rolls 1; and g. The plates 1' are held in position by set-screws 1' which pass through the hubs 1. At one side of the machine, adjacent to the feed table, is arranged a' horizontal color-table 'u on which the cans of color are supported, so as to sup ly the color from time to time to the co orfountain.

The operation of my improved coatingmachine is the same as that of the coatingmachines in general use. After the colorfountain is placed in position, below the fountain-roll, and the loose feed-roll placed in position above the lower feed-roll and the regulating-roll adjusted to the upper part of the fountain-roll, the machine is started and .one sheet after the other fed through the same 'so as to receive the color from the transfer-roll in the usual manner. Owing to the arrangement of .the color-regulatin roll above the fountain-roll, the supply 0' color to the transfer-roll is regulated and thereby a uniform layer of coating transferred to the sheets.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

In a coating-machine, the combination,

with the supporting-frame comprising up-.

right side-standards, and the fountain-roll, of upright bracket-arms provided with slots and wlth laterally extending upper portions, screws on said side-standards passin through said slots and by which said brac et-arms are guided vertically, a fountain supported on the laterally-extending upper portions of said bracket-arms, a transverse shaft journaled in the supporting-frame below said bracket-arms, cams on said shaft engaging the lower ends of said arms, and. means whereby said shaft may be manuallyoperated.

In testimony, that I claim the foregoing as my invention, I have signed my name in presence oftwo subscribing witnesses.
